Used to supply 3 phase power, usually from a pole- mounted transformer, to the user's service head where connection to the service entrance cable is made. To be used at voltages of 600 volts or less phase to phase and at conductor temperatures not to exceed 75°C for polyethylene insulated conductors or 90°C for crosslinked polyethylene (XLP) insulated conductors.
Construction
Conductors are concentrically stranded, compressed 1350-H19 aluminum. Insulated with either polyethylene or XLP crosslinked polyethylene. Neutral messengers are concentrically stranded AAC or AAAC or ACSR. One conductor is manufactured with an extruded ridge for phase identification.
Standards

Note :
Designated sizes are : ACSR 6/1 diameter equivalent and AAC with equivalent resistivity per ASTMB-399 for 6201.Conductor temperature of 90°C for XLR 75°C for Poly; ambient temperatures of 40°C; emissivity 0.9; 2ft./sec/wind in sun. To determine current ampacity by conductor size, please consult The National Electric Code, latest edition.
